Copper minerals and ores are found in both igneous and sedimentary rocks. Mining of copper ores is carried out using one of two methods. Underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels, called adits, to reach the ore. Underground mining is, however, relatively expensive and is ...

Open pit mining is the most common mining technology when it comes to new mines. In this technique, the soil is excavated and the mineral separation and the remaining soil material occurs on the surface. The first step in this process is the extraction of the ore (beta with high mineral grade). How does an underground mine work?

As with many minerals, copper is only considered commercially viable to extract if the concentration of it in an area is high, as the process is very energy intensive and costly. However, a technique called biotechnology, which is used by a handful of companies around the world, can extract copper from ore in a much quicker energy efficient way.

The process of smelting separates the metal from the mineral by heating the mineral in the presence of a material known as a flux. The desired mineral settles to the bottom of the melt and can be separated out. The (unwanted) material at the top of the melt can harden into slag. The smelter is often in a different location than the mine.

For both traditional underground and open pit mining, the rocks may have only a few percent (normally <0.3%) uranium in them. The uranium then has to be removed from the rock and concentrated. The milling process involves crushing and pulverizing the rock into very fine fragments and adding water to create a slurry.
